Glimpses of the past activity of Sgr A* inferred from X-ray echoes in Sgr C

Dimitri Chuard, Régis Terrier, Andrea Goldwurm +6

For a decade now, evidence has accumulated that giant molecular clouds located within the central molecular zone of our Galaxy reflect X-rays coming from past outbursts of the supe…

GW170817 Most Likely Made a Black Hole

David Pooley, Pawan Kumar, J. Craig Wheeler +1

There are two outstanding issues regarding the neutron-star merger event GW170817: the nature of the compact remnant and the interstellar shock. The mass of the remnant of GW170817…

The X-ray reflection spectrum of the radio-loud quasar 4C 74.26

Anne Lohfink, Andrew Fabian, David Ballantyne +11

The relativistic jets created by some active galactic nuclei are important agents of AGN feedback. In spite of this, our understanding of what produces these jets is still incomple…

A powerful flare from Sgr A* confirms the synchrotron nature of the X-ray emission

G. Ponti, E. George, S. Scaringi +21

We present the first fully simultaneous fits to the NIR and X-ray spectral slope (and its evolution) during a very bright flare from Sgr A*, the supermassive black hole at the Milk…

GRB 161219B-SN 2016jca: a powerful stellar collapse

C. Ashall, P. A. Mazzali, E. Pian +26

We report observations and analysis of the nearby gamma-ray burst GRB\,161219B (redshift ) and the associated Type Ic supernova (SN) 2016jca. GRB\,161219B had an isotropi…
